I still think bad idea.

Parent need to understand that they pay on days reserved not days attended. They need all 5 days on some week but only 4 on other week but if you take this person, it will be impossible for you to find another client who just work one day every two week to make up the spot. They need to pay for all 10 days - period.

If you charge $38 a day, then 10 days care adds to $380. Regular hours is 10 hour day which is $3.80 an hour. But if they come for longer hours, you charge $40 a day. 30 mins extra in morning and 30 mins extra at end of day is one whole hour extra a day. But you only charging $2 for that extra hour? Why charge almost half for extra time? Most people charge double for extra time not half. Not super cheap.

This parent has tricky needs but this parent must pay for thier own need. Not up to provider to lose out to fix their family needs.
